Sometimes life just seems to throw everything at you at once and you just think ' what the hell did i do to deserve this!'
Sorry to hear about your paren's health problems, there may be some tough times ahead and you will feel the strain. Hope your brother will help you shoulder some of it.
My motto this year has had to be' just wait and see what tomorrow brings'. There have been good days and terrible ones and to cope with what IS happening you need to try not to worry about what MIGHT happen. Easier said than done, I know.
You're doing a goood thing by helping out so your mum can get a break. The chances are everything will be fine with your dad but if anything should happen you will just do what you have to do. Honestly, you are stronger than you think you are and will cope!
It's also natural to be angry and upset by the news you've been given about your parents. Let it out if you can ( advice from the world's biggest hypocrite - I always feel I have to 'be strong' ) and make sure you get some time to yourself or with friends either to think/ talk things through or just to put everything out of your mind and relax, even if it's only for fifteen minutes.
Do let us know how things are going for your family. AB is always here if you need a shoulder to cry on; God knows I've been here enough myself recently. Take care of yourself. I'll be thinking of you. x
